MAke two piles and spread them apart
Answer/Explanation:
Methanol has a molecular weight (32.04 g/mol), low-boiling point and because of its low boiling point, methanol readily evaporates at room temperature.
Under these specified non-standard conditions, the partial pressure of methanol is lower than its vapor pressure and this explains the reason for the spontaneous evaporation exhibited by methanol.
Even though two grams seemed to disappear or vanish, the law of conversation of mass still holding true. Mercuric oxide, when heated, forms a gas of mercury and oxygen. During the investigation, some gas could have escaped or evaporated.
Answer
36.45 u; X = Cl
Explanation:
The atomic mass of X is the <em>weighted averag</em>e of the atomic masses of its isotopes.
We multiply the atomic mass of each isotope by a number representing its relative importance (i.e., its percent of the total).
Set up a table for easy calculation
.
0.7577 × 34.969 u = 26.496 u
0.2423 × 36.965 u = <u> 8.9566 u
</u>
TOTAL = 36.45 u
X = Cl
